B.2.2.2 Pixel registration

Here, the nodes are centered in the grid cells, i.e., the areas
between grid lines, and the data points represent the average
values within each cell (Figure B.2.
In the case of pixel registration the number of nodes are related
to region and grid spacing by

Thus, given the same region (-R), the pixel registered grids have one less
column and one less row than the grid line registered grids; here we
find .
